A bit of an oddity this - the remaining Torchwood trio of Gwen, Jack, and Ianto, generally take a back seat to the bonkers and enigmatic Agnes Havisham, a Torchwood risk-assessor who comes out of hibernation every few years in order to micro manage the exisiting team. As a previous reviewer has mentioned, writer James Goss captures the key characters' mannerisms and personalities perfectly; Havisham herself doesn't really justify her characters' existence, but there is enough going on to keep the reader's attention, and the globular 'Vam' is a wonderfully obnoxious alien menace.
